Overview
The MURH860CTH is an ultrafast recovery rectifier manufactured by onsemi, featuring a dual common cathode configuration. It supports a maximum repetitive peak reverse voltage of 600 V and an average forward rectified current of 4 A per diode leg. The device exhibits a typical forward voltage drop of 2.8 V at rated current and a maximum reverse leakage current of 10 uA. Its ultrafast recovery time is specified at 35 ns, with a peak non-repetitive forward surge current capability of 100 A. Operating temperatures range from -65°C to +175°C.
Feature Summary
- Ultrafast recovery characteristics minimize switching losses in high-frequency applications
- Dual common cathode configuration enables efficient bridge rectification in compact designs
- High thermal stability allows reliable operation at elevated junction temperatures up to 175°C
Applications
- High-frequency switch-mode power supplies
- Free-wheeling rectification in DC-DC converters
- Output rectification in industrial power management systems
Procurement Notes
Verify the specific suffix 'TH' against official onsemi documentation to confirm package type and tape-and-reel specifications, as standard variants may use different packaging. Ensure compliance with RoHS and REACH requirements for the intended market. Cross-reference the datasheet revision date to confirm parameter validity before finalizing procurement.
Selection Notes
Select this component when designing circuits requiring fast recovery times below 50 ns and moderate current handling up to 4 A per leg. The 600 V rating suits general-purpose AC-DC conversion and isolated DC-DC topologies. Consider the D2PAK or similar surface-mount package for automated assembly and thermal performance needs compared to through-hole alternatives.
Part Context
This part belongs to the MURH series of SWITCHMODE ultrafast rectifiers from onsemi. The series is designed for high-efficiency power conversion applications where reduced reverse recovery charge is critical. It complements other variants in the family offering different voltage ratings and current capacities within the same technological platform.
Replacement Considerations
Compatible substitutes include MURH860CTG and MURHF860CTG, which share identical electrical specifications. Verify that the replacement variant matches the required package style (e.g., D2PAK vs. TO-220FP) and lead-free status to ensure mechanical and regulatory compatibility.
